Specification of Letters Patent.

Application filed October 30, 1917. Serial No. 199,318.

To all whom it may concern:

Be it known that we, J OSEPH LOUIS ADHE- MAR BonEL and EMILIE GRANGE, ne BonEL, citizens of the Republic of France, resid1ng at 2 Rue Notre Dame, Annecy, Haute Savoie, in the Republic of France, have invented certain new anduseful Improvements in Machines for Inserting Retaining-Springs in Cap-Like Members of Press-Buttons or the like, of which the" following is a specification.

The present invention relates to a machine for the purpose'of engaging the retaining springs in' the like member of press buttons, and of forcing the edges of the said cap like members down on to the springs.

This machine is characterized by the combination and arrangement of its various con stituent parts, comprising in particular 1. A positioning tool for the purpose of engagin thespring in the cap" like member of the press button;

2. A tool that serves to force the edges of the cap. like member over the retaining spring; u

3. A pusherfor the purpose ofdlsengaging the spring from the positioning tool so as to make it enter the cap like member of the press button; l

4:. A thrust member that receives the cap like member of the press button, the said thrust member being pierced by a passage through which air may be drawn out or injected for the purpose of holding fast or.

throwing out thecap like member;

5. An air-distributing valve- This machine permits of the rapid manufacture of press buttons,and insuresthe perfeet formation thereof.

By way of example, this invention will be described with reference to the accompanying drawing, in which V Figure 1 shows a plan of the machme as a whole.

member are being turned over the retaining spring.

Fig. 5 is a cross sectional View along the line AA of Fig. 2.

Fig. 6 is an end view of the thrust member, with the cap like member of the press button and the spring.

Fig. 7 shows the air-distributing valve separately in section.

Fig. 8' shows the spring and caplike member prior to their insertion in'theniachin'e. As may be seen from this drawing, the

machine comprises a slide guide a provided with a positioning tool 6, the object of which is to insert the spring 0 in the cap like member d, and with'the tool a, which serves to turn the edges of the cap like member over the spring, these various parts being carried by a sleeve 7. p

The member I) constituting the positioning tool that serves to insert the retaining springs c in the press buttons consists of a blade having a projecting stop 6, a slightly narrowed part b and a notch 6 This blade is normally held in the position shown inf Fig. 2 by a spring 9. It is on this blade that the spring. a to be inserted is placed. I

Surrounding the blade of the positioning tool 6 there is a slidable sleeve h for the purpose of disengaging theretaining spring 0 from the blade I) in order to press it into the cap like member l. Thislsleeve h is pro vided internally with a stop it adapted to cooperate with a stop or projection?) on the blade 5.

Surrounding the sleeve it there is a coil spring 2'. Finally, surrounding the blade I V and the sleeve 72. there is the closing or flang= ingjtool 6, provided with a groove 6 for the purpose of turning the edge of the cap like member (Z over the spring 0.

The closing or fianging tool 6 is rigidly secured to the sleeve 7". Both the positioning tool 6 and the sleeve h are adapted to slide within the tool' e, which, as shown, is made hollow, for the purpose of accommodating these parts.

The various members of the machine are arranged on the table 7' as shown in Fig. I

' of the drawing.

Facing the tool I) is a frame mung frame is slidably mounted thrust member Z, the rear part of which is supported in a guide m,1one "end of which "forms abut ment m 1 Y The' member Z receivesthes. cap-like 'mem}, ber d on its free end, and it is pierced with a passage Z through which air is drawn out or injected for'the-purpose of'holding fast or throwing out the cap like member 6Z2 For this purpose a pipe it connects the passage Z. with the casinw a ofa suitable distributing. valve (Fig. I

The free end of member Z is engaged in a sleeve 0 whlch is pressed against the frame 70 by a spring p.

The thrust member Z is held back when necessary by acatch g, which vcooperates with a notch g from which it is disengagedat the proper time by a cam 1" through the intermediary of a lever 'g pivoted at y and 7 connected with catch g through a' pivoted link g As shown in Fig. 2 catch r .is provided with a slot j Q thrdiighWvhich -..passes a small screw 9 whereby the catch is guided ina' vertical direction.

Atthis moment a vacuum is produced in .1 the passage Z of the thrust member, which 7e, carrying with it as a whole the, position-- causes the cap like inember d: to beheld thereto. r I
